Answer 1

In case you don't want to write custom extension, try manual configuration of 'file association' for '.xlp' files. This will tell VS Code to highlight content of '.xlp' files as language of your choice.

For example, I set it to C# and it looks like this:

Steps for this configuration:

1. Inside of '.xlp' file press ctrl + P to open navigation field,
2. Search for >Change Language Mode,
3. Choose Configure File Association for '.xlp',
4. From dropdown list choose language you like.
